The Go project reports:

syscall, os/exec: unsanitized NUL in environment variables

On Windows, syscall.StartProcess and os/exec.Cmd did not properly check for invalid environment variable values. A malicious environment variable value could exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" set the variables "A=B" and "C=D".
